for theintake opening,'7, in the front upper end of said hopper, respectively. The outer door or lid, 6, is provided with a skirt, 8, secured to the underside thereof,iat its outer edges and designed to fit snugly in the intakeclosure. The lid is hinged on said'hopper for swingingnpwardly, and has the edge thereof adjacentthe chute, notched, the metal portions, 9,1 intermediate said notches being port, 10, for the hinged doors, 5 and 6. The plate support,-10,:is also. notched and the portions,- 11, intermediatethe"notches. are rolled to form hinges for registering with ..the:notohes in the lid, 6, the hinges, 9,- also,

A portion of the' i front hopper wall, 3, near the dischargeopening,4, is'bent atright angles to. form .asupnected by a common pivot rod, 12, extending transversely to permit the lid to swing about ,the pivot rod'foropening. A spring catch,

'13, of any-suitable constructiompreterably asshown, is secured to the frontwall, 3. fof the v chute for holding said lid'infan upright position when open. V I g k The inner door, 5, is of a widthgreater "than the hopper, and .its lateral edges abut 1 i against shoulders, 14, formedbyoofi'settihgQSO the side walls of the hopper adjacent the p 'thedoor will always hang out of plumb which with the, notches on the edgeof Sa aam;

U Thefdoor, 5,is of substantial I weight'and is hingedly supported at a point. forward of the frontwall of thechute so that Thesehin ge members. are connected, common pivotrod, 17,,extending transversely across the chute, below the pivot rod, 1

V ing in the hopper. v The engagement of these adjacent its hinged connection on the side toward the hopper and is positioned so that a second angle iron, 19, which is attached to the'under side ofthelid, 6, will impinge upon it, thus providing a cam action'to-push door, 5', outwardly to uncover the :dischargeopenangles ceases when the lid is raised to the positionindicated A? in- Figure 1, and the of plumb. vThe skirt, 8, of the lid, 6', main- 7' 'tains closure of the intake opening, 7, during 1 lap the interval 'when'the lid is being raised to osition A, and for the upward movement 7 of the lid, 6, releases. pressure of the angle irons against eachother to permit the inner I I I door, 5, toclose the discharge opening, 4:,

Although the inner door, 5, would normally'closethe discharge openingdueto its offi- Vset'hin'ged connection, as the lid is raised to open position B, it is desirable to hold said door positively closed whilefilling the hop- 7 per with refuse, to prevent ofiensive. odors, v dirt, etc. from backing up in therchute and entering the room and 'to prevent} sparks that maybe floating aboutin th'e chute, from contactingrwith therubbish in the, hopper.

sition, it permits the rubbish inthe hopper to be-packed or compressed withoutbeing forced into the chute, this applyingjespecially to lightweight refuse. as wastepapempacking imateria ls, etc. To: thisend, I provide a flexible membershown as a 'chain;20,one end he Ming, secured to the under side oi -the lid 6,

and the other endattached to an adjustable eye bolt 21, secured in acli-p fastened to the adjacentside of-the door, 5', so that'as the lid fcatch, this flexible member becomes taut and holds the door, 5, in closed position. "As the lid-isireleased and lowered to thepositionat ,A, the impingement or" the angle irons of the lid and door, forces said'door outwardly to open-thedischargei opening of the, hopper.
